CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation of U.S. application Ser. No.16/938,308 filed on Jul. 24, 2020, and claims priority to U.S.Provisional Application Ser. No. 63/046,189 filed on Jun. 30, 2020, thecontents of both of which are incorporated fully herein by reference.

TECHNICAL FIELD

Examples set forth in the present disclosure relate to the field ofaugmented reality (AR) and wearable mobile devices such as eyeweardevices.

BACKGROUND

Many types of computers and electronic devices available today, such asmobile devices (e.g., smartphones, tablets, and laptops), handhelddevices, and wearable devices (e.g., smart glasses, digital eyewear,headwear, headgear, and head-mounted displays), include a variety ofcameras, sensors, wireless transceivers, input systems (e.g.,touch-sensitive surfaces, pointers), peripheral devices, displays, andgraphical user interfaces (GUIs) through which a user can interact withdisplayed content.

Augmented reality (AR) combines real objects in a physical environmentwith virtual objects and displays the combination to a user. Thecombined display gives the impression that the virtual objects areauthentically present in the environment, especially when the virtualobjects appear and behave like the real objects.

Reference now is made in detail to the examples illustrated in theaccompanying drawings and discussed below.

FIG. 1A is a side view (right) of an example hardware configuration ofan eyewear device 100 which includes a touch-sensitive input device ortouchpad 181. As shown, the touchpad 181 may have a boundary that issubtle and not easily seen; alternatively, the boundary may be plainlyvisible or include a raised or otherwise tactile edge that providesfeedback to the user about the location and boundary of the touchpad181. In other implementations, the eyewear device 100 may include atouchpad on the left side.

The surface of the touchpad 181 is configured to detect finger touches,taps, and gestures (e.g., moving touches) for use with a GUI displayedby the eyewear device, on an image display, to allow the user tonavigate through and select menu options in an intuitive manner, whichenhances and simplifies the user experience.

Detection of finger inputs on the touchpad 181 can enable severalfunctions. For example, touching anywhere on the touchpad 181 may causethe GUI to display or highlight an item on the image display, which maybe projected onto at least one of the optical assemblies 180A, 180B.Double tapping on the touchpad 181 may select an item or icon. Slidingor swiping a finger in a particular direction (e.g., from front to back,back to front, up to down, or down to) may cause the items or icons toslide or scroll in a particular direction; for example, to move to anext item, icon, video, image, page, or slide. Sliding the finger inanother direction may slide or scroll in the opposite direction; forexample, to move to a previous item, icon, video, image, page, or slide.The touchpad 181 can be virtually anywhere on the eyewear device 100.

In one example, an identified finger gesture of a single tap on thetouchpad 181, initiates selection or pressing of a graphical userinterface element in the image presented on the image display of theoptical assembly 180A, 180B. An adjustment to the image presented on theimage display of the optical assembly 180A, 180B based on the identifiedfinger gesture can be a primary action which selects or submits thegraphical user interface element on the image display of the opticalassembly 180A, 180B for further display or execution.

As shown, the eyewear device 100 includes a right visible-light camera114B. As further described herein, two cameras 114A, 114B capture imageinformation for a scene from two separate viewpoints. The two capturedimages may be used to project a three-dimensional display onto an imagedisplay for viewing with 3D glasses.

The eyewear device 100 includes a right optical assembly 180B with animage display to present images, such as depth images. As shown in FIGS.1A and 1B, the eyewear device 100 includes the right visible-lightcamera 114B. The eyewear device 100 can include multiple visible-lightcameras 114A, 114B that form a passive type of three-dimensional camera,such as stereo camera, of which the right visible-light camera 114B islocated on a right corner 110B. As shown in FIGS. 1C-D, the eyeweardevice 100 also includes a left visible-light camera 114A.

Left and right visible-light cameras 114A, 114B are sensitive to thevisible-light range wavelength. Each of the visible-light cameras 114A,114B have a different frontward facing field of view which areoverlapping to enable generation of three-dimensional depth images, forexample, right visible-light camera 114B depicts a right field of view111B. Generally, a “field of view” is the part of the scene that isvisible through the camera at a particular position and orientation inspace. The fields of view 111A and 111B have an overlapping field ofview 304 (FIG. 3 ). Objects or object features outside the field of view111A, 111B when the visible-light camera captures the image are notrecorded in a raw image (e.g., photograph or picture). The field of viewdescribes an angle range or extent, which the image sensor of thevisible-light camera 114A, 114B picks up electromagnetic radiation of agiven scene in a captured image of the given scene. Field of view can beexpressed as the angular size of the view cone; i.e., an angle of view.The angle of view can be measured horizontally, vertically, ordiagonally.

In an example, visible-light cameras 114A, 114B have a field of viewwith an angle of view between 15° to 30°, for example 24°, and have aresolution of 480×480 pixels. The “angle of coverage” describes theangle range that a lens of visible-light cameras 114A, 114B or infraredcamera 410 (see FIG. 2A) can effectively image. Typically, the cameralens produces an image circle that is large enough to cover the film orsensor of the camera completely, possibly including some vignetting(e.g., a darkening of the image toward the edges when compared to thecenter). If the angle of coverage of the camera lens does not fill thesensor, the image circle will be visible, typically with strongvignetting toward the edge, and the effective angle of view will belimited to the angle of coverage.

Examples of such visible-light cameras 114A, 114B include ahigh-resolution complementary metal-oxide-semiconductor (CMOS) imagesensor and a digital VGA camera (video graphics array) capable ofresolutions of 640p (e.g., 640×480 pixels for a total of 0.3megapixels), 720p, or 1080p. Other examples of visible-light cameras114A, 114B that can capture high-definition (HD) still images and storethem at a resolution of 1642 by 1642 pixels (or greater); or recordhigh-definition video at a high frame rate (e.g., thirty to sixty framesper second or more) and store the recording at a resolution of 1216 by1216 pixels (or greater).

The eyewear device 100 may capture image sensor data from thevisible-light cameras 114A, 114B along with geolocation data, digitizedby an image processor, for storage in a memory. The visible-lightcameras 114A, 114B capture respective left and right raw images in thetwo-dimensional space domain that comprise a matrix of pixels on atwo-dimensional coordinate system that includes an X-axis for horizontalposition and a Y-axis for vertical position. Each pixel includes a colorattribute value (e.g., a red pixel light value, a green pixel lightvalue, or a blue pixel light value); and a position attribute (e.g., anX-axis coordinate and a Y-axis coordinate).

In order to capture stereo images for later display as athree-dimensional projection, the image processor 412 (shown in FIG. 4 )may be coupled to the visible-light cameras 114A, 114B to receive andstore the visual image information. The image processor 412, or anotherprocessor, controls operation of the visible-light cameras 114A, 114B toact as a stereo camera simulating human binocular vision and may add atimestamp to each image. The timestamp on each pair of images allowsdisplay of the images together as part of a three-dimensionalprojection. Three-dimensional projections produce an immersive,life-like experience that is desirable in a variety of contexts,including virtual reality (VR) and video gaming.

FIG. 1B is a perspective, cross-sectional view of a right corner 110B ofthe eyewear device 100 of FIG. 1A depicting the right visible-lightcamera 114B of the camera system, and a circuit board. FIG. 1C is a sideview (left) of an example hardware configuration of an eyewear device100 of FIG. 1A, which shows a left visible-light camera 114A of thecamera system. FIG. 1D is a perspective, cross-sectional view of a leftcorner 110A of the eyewear device of FIG. 1C depicting the leftvisible-light camera 114A of the three-dimensional camera, and a circuitboard.

Construction and placement of the left visible-light camera 114A issubstantially similar to the right visible-light camera 114B, except theconnections and coupling are on the left lateral side 170A. As shown inthe example of FIG. 1B, the eyewear device 100 includes the rightvisible-light camera 114B and a circuit board 140B, which may be aflexible printed circuit board (PCB). The right hinge 126B connects theright corner 110B to a right temple 125B of the eyewear device 100. Insome examples, components of the right visible-light camera 114B, theflexible PCB 140B, or other electrical connectors or contacts may belocated on the right temple 125B or the right hinge 126B.

The right corner 110B includes corner body 190 and a corner cap, withthe corner cap omitted in the cross-section of FIG. 1B. Disposed insidethe right corner 110B are various interconnected circuit boards, such asPCBs or flexible PCBs, that include controller circuits for rightvisible-light camera 114B, microphone(s), low-power wireless circuitry(e.g., for wireless short range network communication via Bluetooth™),high-speed wireless circuitry (e.g., for wireless local area networkcommunication via Wi-Fi).

The right visible-light camera 114B is coupled to or disposed on theflexible PCB 140B and covered by a visible-light camera cover lens,which is aimed through opening(s) formed in the frame 105. For example,the right rim 107B of the frame 105, shown in FIG. 2A, is connected tothe right corner 110B and includes the opening(s) for the visible-lightcamera cover lens. The frame 105 includes a front side configured toface outward and away from the eye of the user. The opening for thevisible-light camera cover lens is formed on and through the front oroutward-facing side of the frame 105. In the example, the rightvisible-light camera 114B has an outward-facing field of view 111B(shown in FIG. 3 ) with a line of sight or perspective that iscorrelated with the right eye of the user of the eyewear device 100. Thevisible-light camera cover lens can also be adhered to a front side oroutward-facing surface of the right corner 110B in which an opening isformed with an outward-facing angle of coverage, but in a differentoutwardly direction. The coupling can also be indirect via interveningcomponents.

As shown in FIG. 1B, flexible PCB 140B is disposed inside the rightcorner 110B and is coupled to one or more other components housed in theright corner 110B. Although shown as being formed on the circuit boardsof the right corner 110B, the right visible-light camera 114B can beformed on the circuit boards of the left corner 110A, the temples 125A,125B, or the frame 105. Flexible PCB 140A is disposed inside the leftcorner 110A and is coupled to one or more other components housed in theleft corner 110A. Although shown as being formed on the circuit boardsof the left corner 110A, the left visible-light camera 114A can beformed on the circuit boards of the right corner 110B, the temples 125A,125B, or the frame 105.

FIGS. 2A and 2B are perspective views, from the rear, of examplehardware configurations of the eyewear device 100, including twodifferent types of image displays. The eyewear device 100 is sized andshaped in a form configured for wearing by a user; the form ofeyeglasses is shown in the example. The eyewear device 100 can takeother forms and may incorporate other types of frameworks; for example,a headgear, a headset, or a helmet.

In the eyeglasses example, eyewear device 100 includes a frame 105including a left rim 107A connected to a right rim 107B via a bridge 106adapted to be supported by a nose of the user. The left and right rims107A, 107B include respective apertures 175A, 175B, which hold arespective optical element 180A, 180B, such as a lens and a displaydevice. As used herein, the term “lens” is meant to include transparentor translucent pieces of glass or plastic having curved or flat surfacesthat cause light to converge/diverge or that cause little or noconvergence or divergence.

Although shown as having two optical elements 180A, 180B, the eyeweardevice 100 can include other arrangements, such as a single opticalelement (or it may not include any optical element 180A, 180B),depending on the application or the intended user of the eyewear device100. As further shown, eyewear device 100 includes a left corner 110Aadjacent the left lateral side 170A of the frame 105 and a right corner110B adjacent the right lateral side 170B of the frame 105. The corners110A, 110B may be integrated into the frame 105 on the respective sides170A, 170B (as illustrated) or implemented as separate componentsattached to the frame 105 on the respective sides 170A, 170B.Alternatively, the corners 110A, 110B may be integrated into temples(not shown) attached to the frame 105.

In one example, the image display of optical assembly 180A, 180Bincludes an integrated image display 177. As shown in FIG. 2A, eachoptical assembly 180A, 180B includes a suitable display matrix 177, suchas a liquid crystal display (LCD), an organic light-emitting diode(OLED) display, or any other such display. Each optical assembly 180A,180B also includes an optical layer or layers 176, which can includelenses, optical coatings, prisms, mirrors, waveguides, optical strips,and other optical components in any combination. The optical layers176A, 176B, . . . 176N (shown as 176A-N in FIG. 2A and herein) caninclude a prism having a suitable size and configuration and including afirst surface for receiving light from a display matrix and a secondsurface for emitting light to the eye of the user. The prism of theoptical layers 176A-N extends over all or at least a portion of therespective apertures 175A, 175B formed in the left and right rims 107A,107B to permit the user to see the second surface of the prism when theeye of the user is viewing through the corresponding left and right rims107A, 107B. The first surface of the prism of the optical layers 176A-Nfaces upwardly from the frame 105 and the display matrix 177 overliesthe prism so that photons and light emitted by the display matrix 177impinge the first surface. The prism is sized and shaped so that thelight is refracted within the prism and is directed toward the eye ofthe user by the second surface of the prism of the optical layers176A-N. In this regard, the second surface of the prism of the opticallayers 176A-N can be convex to direct the light toward the center of theeye. The prism can optionally be sized and shaped to magnify the imageprojected by the display matrix 177, and the light travels through theprism so that the image viewed from the second surface is larger in oneor more dimensions than the image emitted from the display matrix 177.

In one example, the optical layers 176A-N may include an LCD layer thatis transparent (keeping the lens open) unless and until a voltage isapplied which makes the layer opaque (closing or blocking the lens). Theimage processor 412 on the eyewear device 100 may execute programming toapply the voltage to the LCD layer in order to produce an active shuttersystem, making the eyewear device 100 suitable for viewing visualcontent when displayed as a three-dimensional projection. Technologiesother than LCD may be used for the active shutter mode, including othertypes of reactive layers that are responsive to a voltage or anothertype of input.

In another example, the image display device of optical assembly 180A,180B includes a projection image display as shown in FIG. 2B. Eachoptical assembly 180A, 180B includes a laser projector 150, which is athree-color laser projector using a scanning mirror or galvanometer.During operation, an optical source such as a laser projector 150 isdisposed in or on one of the temples 125A, 125B of the eyewear device100. Optical assembly 180B in this example includes one or more opticalstrips 155A, 155B, . . . 155N (shown as 155A-N in FIG. 2B) which arespaced apart and across the width of the lens of each optical assembly180A, 180B or across a depth of the lens between the front surface andthe rear surface of the lens.

As the photons projected by the laser projector 150 travel across thelens of each optical assembly 180A, 180B, the photons encounter theoptical strips 155A-N. When a particular photon encounters a particularoptical strip, the photon is either redirected toward the user's eye, orit passes to the next optical strip. A combination of modulation oflaser projector 150, and modulation of optical strips, may controlspecific photons or beams of light. In an example, a processor controlsoptical strips 155A-N by initiating mechanical, acoustic, orelectromagnetic signals. Although shown as having two optical assemblies180A, 180B, the eyewear device 100 can include other arrangements, suchas a single or three optical assemblies, or each optical assembly 180A,180B may have arranged different arrangement depending on theapplication or intended user of the eyewear device 100.

As further shown in FIGS. 2A and 2B, eyewear device 100 includes a leftcorner 110A adjacent the left lateral side 170A of the frame 105 and aright corner 110B adjacent the right lateral side 170B of the frame 105.The corners 110A, 110B may be integrated into the frame 105 on therespective lateral sides 170A, 170B (as illustrated) or implemented asseparate components attached to the frame 105 on the respective sides170A, 170B. Alternatively, the corners 110A, 110B may be integrated intotemples 125A, 125B attached to the frame 105.

In another example, the eyewear device 100 shown in FIG. 2B may includetwo projectors, a left projector (not shown) and a right projector 150.The left optical assembly 180A may include a left display matrix 177 ora left set of optical strips (not shown) which are configured tointeract with light from the left projector. Similarly, the rightoptical assembly 180B may include a right display matrix (not shown) ora right set of optical strips 155A, 155B, . . . 155N which areconfigured to interact with light from the right projector 150. In thisexample, the eyewear device 100 includes a left display and a rightdisplay.

FIG. 3 is a diagrammatic depiction of a three-dimensional scene 306, aleft raw image 302A captured by a left visible-light camera 114A, and aright raw image 302B captured by a right visible-light camera 114B. Theleft field of view 111A may overlap, as shown, with the right field ofview 111B. The overlapping field of view 304 represents that portion ofthe image captured by both cameras 114A, 114B. The term ‘overlapping’when referring to field of view means the matrix of pixels in thegenerated raw images overlap by thirty percent (30%) or more.‘Substantially overlapping’ means the matrix of pixels in the generatedraw images—or in the infrared image of scene—overlap by fifty percent(50%) or more. As described herein, the two raw images 302A, 302B may beprocessed to include a timestamp, which allows the images to bedisplayed together as part of a three-dimensional projection.

For the capture of stereo images, as illustrated in FIG. 3 , a pair ofraw red, green, and blue (RGB) images are captured of a real scene 306at a given moment in time—a left raw image 302A captured by the leftcamera 114A and right raw image 302B captured by the right camera 114B.When the pair of raw images 302A, 302B are processed (e.g., by the imageprocessor 412), depth images are generated. The generated depth imagesmay be viewed on an optical assembly 180A, 180B of an eyewear device, onanother display (e.g., the image display 580 on a mobile device 401), oron a screen.

The generated depth images are in the three-dimensional space domain andcan comprise a matrix of vertices on a three-dimensional locationcoordinate system that includes an X axis for horizontal position (e.g.,length), a Y axis for vertical position (e.g., height), and a Z axis fordepth (e.g., distance). Each vertex may include a color attribute (e.g.,a red pixel light value, a green pixel light value, or a blue pixellight value); a position attribute (e.g., an X location coordinate, a Ylocation coordinate, and a Z location coordinate); a texture attribute;a reflectance attribute; or a combination thereof. The texture attributequantifies the perceived texture of the depth image, such as the spatialarrangement of color or intensities in a region of vertices of the depthimage.

In one example, the interactive augmented reality system 400 (FIG. 4 )includes the eyewear device 100, which includes a frame 105 and a lefttemple 110A extending from a left lateral side 170A of the frame 105 anda right temple 125B extending from a right lateral side 170B of theframe 105. The eyewear device 100 may further include at least twovisible-light cameras 114A, 114B having overlapping fields of view. Inone example, the eyewear device 100 includes a left visible-light camera114A with a left field of view 111A, as illustrated in FIG. 3 . The leftcamera 114A is connected to the frame 105 or the left temple 110A tocapture a left raw image 302A from the left side of scene 306. Theeyewear device 100 further includes a right visible-light camera 114Bwith a right field of view 111B. The right camera 114B is connected tothe frame 105 or the right temple 125B to capture a right raw image 302Bfrom the right side of scene 306.

FIG. 4 is a functional block diagram of an example interactive augmentedreality system 400 that includes a wearable device (e.g., an eyeweardevice 100), a mobile device 401, and a server system 498 connected viavarious networks 495 such as the Internet. The interactive augmentedreality system 400 includes a low-power wireless connection 425 and ahigh-speed wireless connection 437 between the eyewear device 100 andthe mobile device 401.

As shown in FIG. 4 , the eyewear device 100 includes one or morevisible-light cameras 114A, 114B that capture still images, videoimages, or both still and video images, as described herein. The cameras114A, 114B may have a direct memory access (DMA) to high-speed circuitry430 and function as a stereo camera. The cameras 114A, 114B may be usedto capture initial-depth images that may be rendered intothree-dimensional (3D) models that are texture-mapped images of a red,green, and blue (RGB) imaged scene. The device 100 may also include adepth sensor 213, which uses infrared signals to estimate the positionof objects relative to the device 100. The depth sensor 213 in someexamples includes one or more infrared emitter(s) 215 and infraredcamera(s) 410.

The eyewear device 100 further includes two image displays 177 of eachoptical assembly 180A, 180B (one associated with the left side 170A andone associated with the right side 170B). The eyewear device 100 alsoincludes an image display driver 442, an image processor 412, low-powercircuitry 420, and high-speed circuitry 430.

In some example configurations, the output components of theeyewear device 100 further include additional indicators such as audibleelements (e.g., loudspeakers), tactile components (e.g., an actuatorsuch as a vibratory motor to generate haptic feedback), and other signalgenerators. For example, the device 100 may include a user-facing set ofindicators, and an outward-facing set of signals.

For example, short range XCVRs 520 may take theform of any available two-way wireless local area network (WLAN)transceiver of a type that is compatible with one or more standardprotocols of communication implemented in wireless local area networks,such as one of the Wi-Fi standards under IEEE 802.11.

To generate location coordinates for positioning of the mobile device401, the mobile device 401 can include a global positioning system (GPS)receiver. Alternatively, or additionally the mobile device 401 canutilize either or both the short range XCVRs 520 and WWAN XCVRs 510 forgenerating location coordinates for positioning. For example, cellularnetwork, Wi-Fi, or Bluetooth™ based positioning systems can generatevery accurate location coordinates, particularly when used incombination. Such location coordinates can be transmitted to the eyeweardevice over one or more network connections via XCVRs 510, 520.

The transceivers 510, 520 (i.e., the network communication interface)conforms to one or more of the various digital wireless communicationstandards utilized by modern mobile networks.

The mobile device 401 further includes a microprocessor that functionsas a central processing unit (CPU); shown as CPU 530 in FIG. 4 . Aprocessor is a circuit having elements structured and arranged toperform one or more processing functions, typically various dataprocessing functions. Although discrete logic components could be used,the examples utilize components forming a programmable CPU. Amicroprocessor for example includes one or more integrated circuit (IC)chips incorporating the electronic elements to perform the functions ofthe CPU. The CPU 530, for example, may be based on any known oravailable microprocessor architecture, such as a Reduced Instruction SetComputing (RISC) using an ARM architecture, as commonly used today inmobile devices and other portable electronic devices. Of course, otherarrangements of processor circuitry may be used to form the CPU 530 orprocessor hardware in smartphone, laptop computer, and tablet.

The CPU 530 serves as a programmable host controller for the mobiledevice 401 by configuring the mobile device 401 to perform variousoperations, for example, in accordance with instructions or programmingexecutable by CPU 530. For example, such operations may include variousgeneral operations of the mobile device, as well as operations relatedto the programming for applications on the mobile device. Although aprocessor may be configured by use of hardwired logic, typicalprocessors in mobile devices are general processing circuits configuredby execution of programming.

The mobile device 401 includes a memory or storage system, for storingprogramming and data. In the example, the memory system may include aflash memory 540A, a random-access memory (RAM) 540B, and other memorycomponents 540C, as needed.

The processor 432 within the eyewear device 100 may construct a map ofthe environment surrounding the eyewear device 100, determine a locationof the eyewear device within the mapped environment, and determine arelative position of the eyewear device to one or more objects in themapped environment. The processor 432 may construct the map anddetermine location and position information using a simultaneouslocalization and mapping (SLAM) algorithm applied to data received fromone or more sensors. In the context of augmented reality, a SLAMalgorithm is used to construct and update a map of an environment, whilesimultaneously tracking and updating the location of a device (or auser) within the mapped environment. The mathematical solution can beapproximated using various statistical methods, such as particlefilters, Kalman filters, extended Kalman filters, and covarianceintersection.

In anexample, first user A and second user B may be friends or colleaguesthat interact via the respective eyewear to jointly generate and modifyone or more virtual objects.

FIG. 6A illustrates a display 177A of the first eyewear device 100Ashowing a virtual object 600 in a first frame of reference, shown as avirtual scene 602A, viewable by a first user A. FIG. 6B illustrates adisplay 177B of the second eyewear device 100B displaying the samevirtual object 600 in a second frame of reference, shown as a virtualscene 602B, viewable by a second user B. The displayed virtual scenes602A and 602B are identical to each other, and mirror each other. Eachuser A and user B can manipulate the displayed virtual object 600, suchas by using the input components of the respective eyewear by tapping onanother virtual object 604 and manipulating the second virtual object604 with respect to virtual object 600. The manipulation by one user ofthe virtual object 600 is displayed on the display 177 of the other useras the eyewear 100A and eyewear 100B are synced to each other.

In an example, as shown in FIG. 6A and FIG. 6B, the virtual object 600is illustrated as a building, and the second virtual object 604 is abuilding block that can be added to the virtual object 600. Likewise,the virtual object 604 can be removed from the virtual object 600, suchthat virtual objects can be added, manipulated, and removed as desired.The user collaboration allows the virtual objects to be jointly createdand modified. Other features of a scene can also be included, such as aroadway, parks, and water.

FIG. 7 is a flow chart 700 depicting a method of operation of theaugmented reality application 460 described herein on a wearable device(e.g., an eyewear device). Although the steps are described withreference to the eyewear device 100A and the eyewear device 100B, asdescribed herein, other implementations of the steps described, forother types of devices, will be understood by one of skill in the artfrom the description herein. Additionally, it is contemplated that oneor more of the steps shown in FIG. 7 , and in other figures, anddescribed herein may be omitted, performed simultaneously or in aseries, performed in an order other than illustrated and described, orperformed in conjunction with additional steps.

At step 702, user A of eyewear 100A initiates a shared group taskapplication 460, and then invites user B of eyewear 100B to join ashared group task session, such as by messaging user B via the wirelesscircuitry 436 and network 495. The messaging can be automaticallygenerated by processor 432 when user A clicks on the name or icon ofuser B from a list of available users, such as a list of friends. User Bcan accept the invite and thereby complete the synching of the eyewear100A and 100B and creating the shared group task session.

At block 704, the processor 432 of eyewear device 100A and the processor432 of eyewear device 100B establish a virtual frame of reference foruser A and user B, respectively. This is shown in FIG. 6A and FIG. 6Bwhere the virtual frame of reference is the virtual scene 602A displayedon the display 177A of eyewear 100A, and the virtual scene 602Bdisplayed on the display 177B of eyewear 100B. The user of the eyewearthat first initiates the shared group task application 460 is referredto as user A.

At block 706, user A of eyewear 100A creates input via the inputcomponents to cause processor 432 to display the virtual object(s) 600in the virtual scene 602A. The virtual object 600 can be an objectselected from a list of objects stored in respective memory 434, and canalso be created from scratch by user A. Responsively, the processor 432of eyewear 100B automatically displays the virtual object 600 to user Bin the virtual scene 602B of eyewear 100B. User B can also go first andcreate the virtual object 600 in virtual scene 602B which is then sharedwith user B and displayed in virtual scene 602A.

At block 708, user A creates input to the eyewear 100A, such as bymanipulating the input components on the eyewear 100A, to manipulate thevirtual object 600 in the virtual scene 602A. The user input can, forexample, cause the virtual object 604 to be manipulated with respect tovirtual object 600. The processor 432 of eyewear 100A automaticallysends a message to the processor 432 of eyewear 100B indicating user Ainput to manipulate the virtual object 600 and virtual object 604. Theprocessor 432 of eyewear 100A also automatically sends a message to theprocessor 432 of eyewear 100B indicating user A modifications of thevirtual scene 602A.

In the example shown in FIG. 6A, the user A input can cause the blockcomprising virtual object 604 to be stacked on the virtual object 600comprising a building. In the example of FIG. 6C, the user A input cancause the watering container 604A to illustrate watering the plant orflower 600.

At block 710, user B likewise creates input to the eyewear 100B, such asby using the input components of the eyewear 100B, to manipulate thevirtual object 600 in virtual scene 602B. The user B input can, forexample, cause the virtual object 604 to be manipulated with respect tovirtual object 600. The processor 432 of eyewear 100B also automaticallysends a message to the processor 432 of eyewear 100A indicating the userB input to manipulate the virtual object 600.

In the example shown in FIG. 6B, the input B can cause the blockcomprising virtual object 604 to be stacked on the virtual object 600comprising a building. In the example of FIG. 6D, the user B input cancause the watering container 604B to illustrate watering the plant orflower 600.

At block 712, the processor 432 of eyewear 100B receives the messagefrom eyewear 100A via network 495, and translates the received messageto manipulate the virtual object 600 and virtual object 604 displayed bydisplay 177B to match the manipulation illustrated by the display 177Aof eyewear 100A. Likewise, the processor 432 of eyewear 100A receivesthe message from eyewear 100B via network 495, and translates thereceived message to manipulate the virtual object 600 and virtual object604 displayed by display 177A to match the manipulation illustrated bythe display 177B of eyewear 100B.

At block 714, the processor 432 of eyewear 100B causes the display 177Bto display the manipulations of user A in the virtual scene 602B ofeyewear 100B, and the processor 432 of eyewear 100A causes the display177A to display the manipulations of user B in the virtual scene 602A ofeyewear 100A.

The resulting virtual scene 602 jointly created during the virtualsession can be stored by each user in memory 434 of the respectiveeyewear 100A and 100B, and also on the server system 498 for lateraccess, further revisions, and sharing to other users.

FIG. 8A shows a perspective from the user point of view through thedisplay of the eyewear device 100. Here the object 806 includes a key.The key may be manipulated in its position or orientation as indicatedby the arrows shown in FIG. 8A. The user 801 controls the position andorientation of the object 806 using hand gestures 803. The physicalenvironment may also include a second object 805, which is in thisexample in the form of a lock. FIG. 8B shows an example menu ofavailable hand gestures and movements used to control the first object806. The menu may be displayed on the display system of the eyeweardevice 100 responsive to user input, including for example selecting amenu option on the display.

In one example, as illustrated in FIG. 8C, a virtual identifier (such asvirtual hand 810) is overlaid on the display 177 adjacent the virtualobject being manipulated (e.g., key 806) to provide the user with visualfeedback regarding which object they are manipulating. In a virtualenvironment where multiple users are manipulating objects, the virtualidentifiers for all users (e.g., with different colors representingdifferent users) may be overlaid on the displays 177 of all users toprovide each user with visual feedback regarding the object they aremanipulating and the objects others are manipulating. In anotherexample, as illustrated in FIG. 8D, another type of virtual identifier(such as virtual ray 812) extends from the user's physical hand to thevirtual object being manipulated to provide the user with visualfeedback regarding which object they are manipulating. The other type ofvirtual identifier illustrated in FIG. 8D may be used instead of or inaddition to the type of virtual identifier illustrated in FIG. 8D.

FIG. 9 shows a list of hand gestures recognized by the eyewear device100. The list may be updated or customized as desired by the user. Thegestures may be assigned to one or more control aspects of the object bythe user, or may be set by a particular game or program software loadedinto the memory of the eyewear device 100. The gestures may also includeuser defined gestures that can be captured by the eyewear device 100,and saved into memory and assigned to a particular command of theeyewear device, for controlling an object in the memory of the eyeweardevice.

Any of the functionality described herein for the eyewear device 100,the mobile device 401, and the server system 498 can be embodied in oneor more computer software applications or sets of programminginstructions, as described herein. According to some examples,“function,” “functions,” “application,” “applications,” “instruction,”“instructions,” or “programming” are program(s) that execute functionsdefined in the programs. Various programming languages can be employedto develop one or more of the applications, structured in a variety ofmanners, such as object-oriented programming languages (e.g.,Objective-C, Java, or C++) or procedural programming languages (e.g., Cor assembly language). In a specific example, a third-party application(e.g., an application developed using the ANDROID™ or IOS™ softwaredevelopment kit (SDK) by an entity other than the vendor of theparticular platform) may include mobile software running on a mobileoperating system such as IOS™, ANDROID™ WINDOWS® Phone, or anothermobile operating systems. In this example, the third-party applicationcan invoke API calls provided by the operating system to facilitatefunctionality described herein.

Hence, a machine-readable medium may take many forms of tangible storagemedium. Non-volatile storage media include, for example, optical ormagnetic disks, such as any of the storage devices in any computerdevices or the like, such as may be used to implement the client device,media gateway, transcoder, etc. shown in the drawings. Volatile storagemedia include dynamic memory, such as main memory of such a computerplatform. Tangible transmission media include coaxial cables; copperwire and fiber optics, including the wires that comprise a bus within acomputer system. Carrier-wave transmission media may take the form ofelectric or electromagnetic signals, or acoustic or light waves such asthose generated during radio frequency (RF) and infrared (IR) datacommunications. Common forms of computer-readable media thereforeinclude for example: a floppy disk, a flexible disk, hard disk, magnetictape, any other magnetic medium, a CD-ROM, DVD or DVD-ROM, any otheroptical medium, punch cards paper tape, any other physical storagemedium with patterns of holes, a RAM, a PROM and EPROM, a FLASH-EPROM,any other memory chip or cartridge, a carrier wave transporting data orinstructions, cables or links transporting such a carrier wave, or anyother medium from which a computer may read programming code or data.Many of these forms of computer readable media may be involved incarrying one or more sequences of one or more instructions to aprocessor for execution.
